The full mapping of a new gas turbine axial compressor at different speeds, IGV settings and pressure ratios (from choking to surge) has been performed utilizing a complete gas turbine with a suitable set of modifications.

The main additions and modifications, necessary to transform the turbine into the Compressor Test Vehicle (CTV), are:

- Compressor inlet throttling valve addition

- Compressor discharge bleed valve addition

- Turbine 1st stage nozzle area reduction

- Starting engine change (increase in output and speed range).

This method has been successfully employed on two different single shaft heavy-duty gas turbines (with a power rating of 11MW and 170 MW respectively).

The paper describes the theoretical basis of this testing method and a specific application with the above mentioned 170 MW machine.
